Amygdalus scoparia has been reported for the first time against the plant pathogenic bacteria.The antimicrobial activity of the methanolic extract of Amygdalus scoparia was evaluated inthis research.The extract was evaluated against 7 phytopatogene (Pseudomonas viridiflava,Pseudomonas syringae pv. Syringae, Rathayibacter rathayi, Xanthomonas campestris pv.Campestris, Xanthomonas arboricola , Agrobacterium sp and Rathayibacter tritici) .Methanolic extract showed significant activity on this bacteria.The maximum antibacterialactivities were observed on Xanthomonas campestris pv. Campestris, Rathayibacter rathayi,Rathayibacter tritici.
